How are fat digested in our body? Where does this process take place?

Digestion of fat takes place in the small intestine. Fat reaches the small intestine in the form of large globules. The liver releases bile juice which emulsifies the fat i.e. it breaks down the large globules into smaller globules.

When does digestion begin?

The digestion process begins when you start chewing your food.

What are the tiny particles that are packaged into fat and cholesterol?

During this process, fat and cholesterol are packaged into tiny particles called chylomicrons.

What enzyme breaks down proteins?

For example, lipase aids in fat digestion, while amylase helps break down carbohydrates, bromelain , and papain. Bromelain and papain are both enzymes that help break down proteins. They can be found in pineapple and papaya. A study in 2013.

Why is fat important to the body?

Fat supports several of your body’s functions and gives your body the energy that it needs. Fat also helps your body absorb important vitamins and gives your body essential fatty acids that control inflammation, improve brain health, and more. The amount of time that fat takes to digest varies from person to person and between men and women.

Which organ breaks down fats?

Small intestine. The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.

What is the process of swallowing food?

2. Esophagus. When you swallow, a series of muscle contractions called peristalsis moves the food through your esophagus and into your stomach. 3. Stomach. Your stomach lining produces acids and enzymes that break down your food further so that the foods can pass to the small intestine. 4.

Where is bile stored in the body?

Your liver produces bile that helps you digest fats and certain vitamins. This bile is stored in the gallbladder. These digestive juices are delivered to your small intestine through ducts where it all works together to complete the fat breakdown.

What enzymes are used to digest proteins?

These two enzymes work best at specific pH while in test tube P2, contained the pepsin solution and the 0.1M HCl and the acidic mixture activated the enzymes to digest the proteins, so musky solution occurred. In test tube P9, contained the pepsin solution and the 0.1 M sodium carbonate and the alkaline mixture prevent the enzymes from being activated to digest the proteins, so no protein digestion took place. In test tube T2, contained the trypsin solution and the 0.1 M sodium carbonate and the alkaline mixture prevent the enzymes from being activated to digest the proteins, so no protein digestion took place. In test tube T9, contained the trypsin solution and the 0.1M sodium carbonate and the alkaline mixture activated the enzymes to digest the proteins, so musky solution occurred. Meanwhile, in test tube PC and TC, there's no protein digestion since don't have any suitable environment for enzyme to activated. The optimal conditions for protein digestion in the stomach would be an acidic environment of pH 2 meanwhile, the optimal conditions for protein digestion in the small intestine would be an alkaline environment of pH 8. DISCUSSION 4.2 Starch is a polysaccharide that has to be broken down into free sugar molecules (monosaccharides)before absorption can take place. In test tube A1 and A2, contained glucose solution only. Iodine solution had been added to A1 and no color change occurred which means no presence of starch meanwhile Benedict's reagent had been added to A2. Test tube A2 been incubate in boiling water and the color changes from blue to light orange. This change shows that the presence of glucose. In test tube B1 and B2, contained starch solution only. Iodine solution had been added to B1 and the color turns to dark blue which means the presence of starch meanwhile the Benedict's reagent had been added to B2.Test tube B2 been incubate in boiling water and there's no color change which means no presence of glucose. In test tube D1 and D2, contained starch solution and untreated amylase. Iodine solution had been added to D1 and there's no color change which means no presence of starch meanwhile the Benedict's reagent had been added to D2. Test tube D2 been incubate in boiling water and the color change from blue to orange color which means the presence of glucose. In test tube E1 and E2, contained starch solution and acidified amylase. Iodine solution had been added to E1 and the color turns to dark blue which means the presence of starch meanwhile the Benedict's reagent had been added to E2. Test tube E2 been incubate in boiling water and the color change from blue to orange color which means the presence of glucose.

How do bile salts and lipase work?

DISCUSSION 4.3 Digestion of lipid in humans, bile salts and lipase act on fat in the duodenum. The bile salts are produced by liver and stored in gall bladder. Lipase is a constituent of pancreatic juice, which is produced by pancreas. In this experiment, you will investigate the action of bile salts, lipase and their role in fat digestion. When fats are hydrolysed, fatty acids and glycerol are released. The presence of acid, creating a relatively low pH, may be used as indication that hydrolysis has occurred. The presence of acid can be detected using a pH indicator (example: phenolphthalein). At alkaline condition (pH above 10), phenolphthalein solution is pink. When acid content is high, phenolphthalein will gradually change its color from pink to colorless. In test tube A, contained lipase and bile and the colour change from light pink to green which means the presence of lipid. The expected result should be pink but there's a contamination substance in the test tube which makes the result turns out with green. The expected result should be no presence of lipid in test tube A. The enzyme activity increased with an initial increase in pH and optimum activity was noted at pH 8 suggesting alkaline nature of the enzyme. the lipid is not digested in this test tube. In test tube B, contained lipase and distilled water and the colour change from light pink to pink which means there are no presence of lipid. The expected result should be colorless but there's a contamination substance in the test tube which makes the result turns out with pink . The expected result should be no presence of lipid in test tube B. Lipid are digested in this test tube. In test tube C, contained distilled water and bile and the colour change from light pink to colorless which means there no presence of lipid. The expected result should be pink but there's a contamination substance in the test tube which makes the result turns out with colorless. The expected result should be presence of lipid in test tube C. lipid are not digested. Bile is composed of bile acids and salts, phospholipids, cholesterol, pigments, water, and electrolyte chemicals that keep the total solution slightly alkaline (with a pH of about 7 to 8). lipid is digested in this test tube. In test tube D, contained lipase and bile (24 degree Celsius) and the colour change from light pink to pink which means there presence of lipid. lipid are not digested in this test tube. The lipase enzyme will hydrolysed fats most efficiently at a temperature of about 37 – 40˚C, as this is close to our human body temperature (37˚C) and matches the temperature of the digestive organs in which lipase acts

What is the first step of lipid digestion?

The first step of lipid digestion that breaks up large fat globules into smaller pieces by chemicals called BILE SALTS that are produced by the liver and stored in the gallbladder

Does lipase help with fat digestion?

PINK. NO fat digestion would occur due to WRONG ENZYME. LIPASE needed for fat digestion, not amylase

What is digestion experiment?

This digestion experiment is a great way to talk through how to run a basic science experiment with your kids. There is a clear experimental setup, control group, and variable groups. Plus this experiment can be done pretty quickly, which is perfect for young children.

How to run your stomach experiment?

Step 1: Take the control bag and set it aside. Don’t do anything to this bag. Step 2: Take the dry bag and have your child squish it up with the bread inside. Once they have squished it for a few minutes, set it aside. Step 3: Take the wet bag and add 1/4 cup of water.

What is control group in an experiment?

Control: The control group in an experiment is the group that you don’t do anything special to. You set it up like the rest of the experiment, but then just leave it. No big changes at all. The control group helps us see if what we are doing in the experiment is actually having an impact.

Why does hydrochloric acid break down food?

Hydrochloric acid breaks down a lot of the food so we can digest it and get the nutrients we need. There are also digestive enzymes that have specific jobs like breaking down proteins. In our experiment, we used water to represent the stomach juices.

Do we chew food before digesting it?

Our stomachs work a little differently than this experiment, in that we chew up our food before we digest it, but the main idea holds true.

When does digestion begin?
